The Bumberry sleeper is a one-piece, one -size diaper that works perfectly for night-time. In fact, this product is recommended exclusively for the night and not the day*. The diapering involves just a single step. The sleeper has two partially stitched wet free inserts on either side of the diaper which helps adjust absorbency and saves time. The overlapping wet free inserts are made of 2 layers of microfiber each and an additional wet-free fabric that keeps the baby’s bum dry. There’s an additional pocket to cater to the needs of heavy wetters. We recommend using a fully prepped Bumberry Hemp insert inside the pocket for longer diapering hours and a fully rested, wet free happy baby in the morning.
